Resistance；
This Intelligent electronic control system is in use, first check for hole condition, if meets pumping unit service condition, if can be with by following
Operating steps booting:
Step 1: first main power source is powered by circuit breaker Q F, then main control loop obtains electric, while driving can pass through SB3/
SB4 walks up and down；
Step 2: open power-on button SH1, then KM1 be powered be attracted, frequency converter B PQ obtain electric while secondary control loop obtain it is electric；
Step 3: zero servo knob XB1 is opened, the operation of frequency converter B PQ zero-speed, while power loss brake actuator is opened；
Step 4: the zero point that zero point limits close switch XW2 is found by electronic descending button SB1 and electronic uplink button SB2,
Zero point is the starting point that stroke calculates；
Step 5: setting stroke parameters by frequency converter panel: A4-22/A4-23 is line-spacing in zero point, A4-24/A4-25 zero
Point Bottom Runby；
Step 6: opening starting/parking knob XB2, motor starts positive and negative rotation operation, observes sucker rod operating status, adjustment
Other relevant parameters: regulating the speed, rotation rotation current potential table RW, until sucker rod jig frequency is suitable；
Such as meet special circumstances, need to stop in emergency, can pass through two ways: scram button SBT promptly stops for frequency converter
Vehicle；Cut-off button ST1 forces parking for power loss brake, and furthermore to protect oil pump, the excess of stroke is not run sucker rod, if uplink limits
It limits close to switch XW1 and downlink close to switch XW3, if excess of stroke self-actuating brake.
